AUTOMOBILE RADIATOR CONSTRUCTION.

Application filed July 16,

This invention relates in general to automobile radiator constructionand more particularly to an improved construction and arrangement of theradiator core, shell and neck so that various types of radiator caps maybe securely locked on said necks.

At the present time, the conventional radiator construction isto have acore or cooling section separate from and fastened to an outer shell.The core is provided at its top with a neck, permanently fastenedthereto, for the purpose of filling the core wlth a cooling medium. Theusual method of fastening the core into the shell is by bolts or othermeans so that should it become necessary to repair or replace the core,the core can be removed from the shell by removing the cap from the neckand unfastening the bolts so that the shell can be pulled outwardly fromthe bottom of the core and then raised upwardly until the top of theshell is lifted sufficiently high to clear the top of the neck whichextends throughan opening in the top of the shell. I

In providing a theft-proof radiator neck cap, it has been necessaryheretofore to incorporate in it some device thatiwill facilitate theremoval of the cap from-the neck, when it becomes necessary to removethe shell for purposes of repair or replacement of the core. The removalof these theft-proof radiator neck 'capsis attimes a very inconvenient,tedious and difficult operation. With the present day type of radiatorconstruction, these caps must be removed before the shell can be liftedfrom the core because the caps are larger than the opening in the top ofthe shell and consequently will not pass through such opening.

Objects of the invention are the provision of aradiator constructed sothat such theftproof caps may be employed on the radiator necks and thecore removed from the shell without removal of the cap from the neck;

the'provision of a radiator construction in which the neck is detachablefrom the core and shell to permit removal of the core from the shell forpurposes of repair or replacements; the arrangementof the parts in sucha construction, so that the neck will be locked against removal whilethe parts are in assembled relation and permitting the removal of saidneck only upon partial detachment of the shell from the core; and suchother ob- 1924. Serial No. 726,236.

j ects and advantages of the invention as may be found to obtain in thestructurehereinafter set forth and claimed.

In the accompanying drawings, forming a part of this speciiicatlon, andshowing for,

purposes of exemplification a preferred form and manner in which theinvention may be embodied and practiced, but without limiting theclaimed invention specifically to such. illustrative instance orinstances:

Figure 1 is a front elevational view of an automobile radiator embodyingmy invention, g p

Fig. 2 is a side elevational'view of the same. i

Fig. 3 is a top plan view of the radiator neck and cap therefor.

Fig. 4 is a front elevational View, parts being shown in section, of theradiator neck and cap therefor.

Fig. 5 is a vertical cross-sectional view taken 011 the line 5-5 of Fig.4. 1

On the drawings, 10 is the radiator shell having upwardly extendingsides '11 and a curved top 12. Brackets 13 having apertures 14 thereinare provided at the lower portions of the sides 11 to secure the shellto similar brackets on the core. Thetop 12 of the shell isprovided withan opening 15 and portions of material 15 about said opening are cutaway to provide slots 16in the shell which re 7 i ceive projections onthe neck. The core or cooling section 17 is formed separate from theshell and is provided with brackets 18- at the lower portions of itssides, said brackets having apertures:v which register with theapertures in the brackets 13 and through which means may pass to securethe core within the shell. The bottom 19 of the shell is provided withbolts 20 that also serve to keep the shell in proper position on thecore. The top 21 of the core is provided with anaperture 22 andextending upwardly from thisopening is an annular collar 23 which is,

permanently clinched at 241- to the material about the aperture 22 inthe top 21. Atits' upper end the collar is threaded on its outer surface25 to receive the threaded lower end 26 of theremovableradiator neck 27so that the neck can be removab'ly secured on the core and in order toprevent possible leakage through the joint between the portions 25 and26, there is provided at the lower end of the removable neck a gasket28. The cy- 29 that fit into the slots 16 when the shell is in the coreuntil the top of the shell clears the top of the projections, therebyreleasing the neck from the shell with suflicient clearance to permitunscrewing of the neck from the collar. A filter opening cap 32 ishinged to the front 33 of the upper end of the neck, said cap having acurved slot 33 providing a cam surface upon which the bale 30 rides tohold the cap tightly down in the. top of the neck to close the filleropening. j

To assemble the radiator, the ends of the bale 30 are withdrawn fromtheprojections 29 and the neck then insertedthrough the openingin the topof the shelluntil the top of the projections 29 is beneath thetop of theshell, then the neck is screwed tightly down on the threaded end of thecollar, then the shell is lowered so that the projections 29 extend intothe slots 16 which prevents further rotation of the'neck. After theshell is so assembled it is fastened to the core at its sides and bottomand the ends of theibale 30 are inserted in the openings in theprojections 29.,

the neck can be lifted out of the shell and the shell lifted off of thecore.

From the foregoing it will be noted that the shell can be removedfromthe core without removing thecap from the neck; that the neck cannot beunscrewed from the core while the shell is normally assembled onto thecore that anornamental cap or other device can be locked or permanentlysecured to the neck and yet permit removal of the shell from the core;that the neck and its attached cap cannot be removed until after theshell is released from the bottom of the core and also released from thesides of the core, and to do this it is necessary to unfasten thesecuring means on the inside of the shell.

MThisinvention as hereinabove set forth embodied in a particular form ofconstrue t'ion but maybe variously embodied within the scopeof theclaims hereinafter made.

, Those features of the invention exemplified in the foregoingdescription which relate moreparticularly to the. locking of haremovable neck and a device extending from the upper part thereof inposition by the shell when assembled on the core and to the removal ofthe neck and the device only when the shellis detached or partially removed from the core are made the subject matter of my copendingapplication for Letters Patent of the United States, filed July 16,1924, Serial No. 726,237.
